摘　　要：数字孪生技术是近年发展起来的工业数字化技术,本文针对深海采矿系统介绍了动态数字孪生系统的构建过程。深海采矿系统结构复杂、操作难度大、环境极端、过程可视化困难。建立深海采矿动态数字孪生系统,对采矿过程进行全生命周期进行可视化监测与数据管理,实现交互控制。本文针对深海采矿系统物理实体建立了高精度、多尺度数字模型,实现了采矿系统物理空间与数字空间状态信息映射,通过物理空间状态信息驱动数字模型实时更新状态,对物理实体动态行为进行精准映射。对该系统的应用框架、关键技术、开发流程以及运行流程进行了说明,阐述了基于状态诊断的深海采矿动态数字孪生系统开发过程。本研究在深海采矿作业中具有重要意义。Digital twins are a kind of digital industrial technologies developed in recent years.This paper introduces the construction process of dynamic digital twin system for deep-sea mining system.Deepsea mining system has a complex composition,complicated operation procedure,and extreme working environment.It is of great significance to establishing dynamic digital twin system for deep-sea mining system to carry out visual monitoring and data management for the whole life cycle of mining process,and realize interactive control in the deep-sea mining operation.In this paper we establish a high-precision and multi-scale digital model for the physical entities of deep-sea mining system,which maps the mining system from physical object to digital space to drive the digital model with updated status collected from physical space.The application framework,key technologies,development process and operation process of the system are explained,and the development process of dynamic digital twin system for deep-sea mining based on state diagnosis is expounded,which is of great significance in deep-sea mining.
